Artbeschreibung
Geographical Origin and Habitat: Atheris squamigera is native to the rainforests of Central and Western Africa, with documented populations in Cameroon, Gabon, the Democratic Republic of the Congo, Uganda, and western Kenya. It primarily inhabits dense, low-growing shrubs, primary rainforest canopies, and secondary forest edges, often near watercourses.
Taxonomy and Genetics: A member of the family Viperidae and the subfamily Viperinae. The genus Atheris consists of specialized arboreal vipers. Scientifically, A. squamigera is famous for its high genetic polymorphism, which causes extreme color variations among individuals in the same geographic populations. No subspecies are currently recognized.
Behavior and Habits: Strictly nocturnal and arboreal. It relies on its strong prehensile tail to anchor itself to branches while waiting in ambush for prey. It is a classic sit-and-wait predator. The species possesses a potent hemotoxic venom capable of causing severe systemic damage in humans. They are generally calm but strike with explosive speed.
Morphology: Typically reaches a length of 50-70 cm, with females usually being larger than males. Its body is covered in heavily keeled, leaf-shaped scales that give it a spiny, rough appearance. The head is broad, triangular, and distinct from the neck. Coloration is highly variable, ranging from bright green, yellow, and orange to red, brown, or black.
Pflege, Zucht und Mitbewohner
Terrarium Setup: A vertically oriented terrarium of at least 60x40x60 cm is required for a single adult. The enclosure must feature a secure lock. Provide multiple climbing branches, vines, and dense foliage (live plants like Pothos are ideal) to create arboreal hideouts. Use a moisture-retaining substrate such as cypress mulch or coco coir.
Lighting and Heating: Establish a daytime thermal gradient of 24-27°C, with a localized basking spot of 30°C using an overhead heat source secured away from the snake. Nighttime temperatures should drop to 20-22°C. A low-output UVB light (5.0) should be provided on a 10-12 hour cycle to support normal physiological processes.
Humidity and Hydration: Maintain high humidity levels between 70% and 85%. Mist the terrarium thoroughly every evening with clean water. These vipers rarely drink from standing water bowls, preferring to lick water droplets off leaves, branches, or their own skin. Ensure the terrarium has good cross-ventilation.
Feeding and Supplementation: Carnivorous. Feed appropriately sized frozen-thawed mice using long feeding tongs. Never feed by hand. Feed juveniles every 7-10 days and adults every 2-3 weeks. Dust prey with multivitamin and calcium supplements once a month, avoiding over-supplementation.
Compatibility: Strictly solitary. Do not cohabitate. Housing multiple individuals together can cause severe stress and potential fights. Due to its medically significant venom, this species must only be kept by experienced keepers using hooks, shift boxes, and adhering to strict venomous snake safety protocols.
Health and Common Diseases: Susceptible to respiratory infections if the air becomes stagnant due to poor ventilation. Skin blister disease and scale rot can occur if the substrate is too wet. Dehydration is a significant risk if spraying is neglected. Ensure access to an experienced exotic animal veterinarian.

Reptilienprofil
- Diät
- Carnivore
- These vipers are ambush predators that feed mainly on small mammals, frogs, and lizards in the wild. In captivity, they can usually be transitioned to a diet of appropriately sized rodents, such as mice or small rats. Feeding should occur every one to two weeks depending on the age and size of the snake.

- Lebensstil/Mikrohabitat
- Arboreal
- Arboreal species spend the majority of their lives in trees and shrubs, requiring vertically oriented enclosures with climbing branches. Terrestrial species need ample floor space with hiding spots among the leaf litter. Both require specific temperature and humidity gradients to thrive.
- Aktivitätszyklus
- Nocturnal
- These snakes are primarily nocturnal or crepuscular, becoming most active during the evening and night. During the day, they often rest coiled on branches or concealed in vegetation. Their activity levels can increase significantly after a period of rain or during the breeding season.
- Sozialität
- Gregarious
- They are typically ambush hunters, relying on their camouflage to remain undetected by both prey and predators. When threatened, they may adopt a defensive posture, hiss, or strike rapidly. They are generally not aggressive but will defend themselves fiercely if provoked.
- Reproduktion
- Ovoviviparous
- Most of these species are viviparous, giving birth to live young after a gestation period of several months. The neonates are fully independent and venomous from birth. Breeding often requires a cooling period or specific environmental cues to simulate natural seasonal changes.
- Handhabungstoleranz
- Display only
- Handling must be strictly avoided except when absolutely necessary for husbandry or medical reasons. Always use appropriate tools such as snake hooks or tongs to move the animal safely. These are highly venomous species, and a bite can result in severe medical consequences.
- Brumation
- Nicht erforderlich
- Depending on their natural range, some may undergo a mild winter cooling period to stimulate breeding. This is not a deep brumation but rather a slight drop in temperature accompanied by reduced feeding. Tropical species may not require any significant seasonal changes in captivity.
- Häutung
- Periodic
- Shedding occurs periodically as the snake grows, heralded by the eyes turning a milky blue color. During this time, they should be left undisturbed and humidity should be slightly increased to facilitate a clean shed. A healthy snake will shed its skin in one complete, unbroken piece.
